Why I got different responses if I’m using exactly the same config.json in both cases?

Scenario 2 (After deleting both sync_gateways I still get responses):

I deleted both sync_gateways from my couchbasecloud dashboard.
When I type http://sync.couchbasecloud.com/restaurant/ and/or http://sync.couchbasecloud.com/test_/ I still get the same responses. I did this on different browsers (IE and Chrome) and I got the same results.
Any ideas?
Is there a “time window” on the couchbasecloud server that maintain sessions for some time after sync_gateways are created even after when you explicitly delete them or change settings?
